To all whom it may concern:

Be'it known that I, HERBERT TOLPU'I'I,

of Great 7 Britain, residing at Heele} Mil s, road, Sheflield, England, have 1' invented a certain Improved Polishing Mixture or" Composition, of which the following is a specification.

This invention relates to a new or improved mixture or composition for use in polishing is desired to produce a bright or highly Heretofore polishing com sitions; have generally oonslsted or have b en composed of tallow, stearin, or other. greasy material as a base to'which latter have been added, crocus, rou e or other so-called polishing powder an :this mixture then cured or molded into a stick or other desire formand mixture in one instance it has been stated that unslaked lime ma be added in such composition but that't ere would then be certain drawbacks, in this mixture notably that the moisture v01E the air would efiect a occurred in such: previously knowni'compost tionithe latter could not rodifce' a bright and] highly polished su ace or effect a pglishing actioni or result; such. as: can

has been proposed to make a composition of stearin and calcined magnesia an an oil for:

use as a metal olish.

My improve composition consists of a' Specification of Letters Patent. Patented Ma1fl25', 1913, Application filed mi 1, 1912. Serial 110. 707,139.

mixture'of a suitable hydrated 'oxid, referably admixed with powdered metallic end, and an agglutinant binder, such as stearin,

tallow, Vaseline, etc. The" composition canbe advantageously produced by maintaining a supply of stearin, or votherfatty binder,

at a temperature somewhat above its melting point, and in stirring such melted binder while-gradually adding thereto a suitable amount of thoroughly slaked and disinte grated lime admixed. with powdered metallic ead. I have found. that a hi hly advamtageous compositionis produce .by mixing 1 with the binder four or ;five. times of its weight of slakedlimeand .a relatively small v amount of powdered metallic lead. allowed to'cool and in makingthe aforesaid This mixture or composition may then be "run into suitable molds, shapes or receptacles and allowed tos'olidify. I ma pack or in store it in airtight orvacuum receptacles or I may coat troduce the said mixture an the mixture in: suitable sized masses with a protective coating.
